1. First determine the atmosphere the Model C Release is used for.

Model C-1 is used for general purposes, non-corrosive atmospheres and is more sensitive to response of heat.

Model C-2 release shall be used for corrosive or seawater air atmospheres and as indicated by spacing information is

less sensitive to heat.See technical data pages for Model C-1 and C-2 Thermostatic Release devices for specific details of product.

All information required under inside spacing.

1b. f individual or groups of equipment, determine

Size and shape.

2. Note characteristics of and location of special features

Monitors and skylights note size and depth.

Decks size and height.

Heat producing equipment note direction of normal heat output.

Probable sources of fire.

3. Select the release spacing chart for the type of situation.

4. f a large semi-enclosed building is involved, follow the rules for inside spacing when placing the interior releases.5. n covering individual pieces or groups of equipment initially, lay out the releases so they will be as close as possible to the

probable source of fire. Then fill out coverage using the appropriate chart. Try to put releases so they are in the path of fire

spread and/or downwind from fire.

6. When covering a number of individual pieces of equipment in an area, check to see if releases protect more than one piece

of equipment. Area coverage may be more desirable.

7. Release hoods should be used for protection of the release from weather or physical damage such as under grating floors

or where release may be subject to accumulation of dirt. Hoods have little or no value as heat collectors.

8. t may be desirable to place 160 F (71 C) fixed temperature release at preferred locations where the fire may originate o

be confined for a short time. n particular, fixed temperature release may be located under tanks and under inside equipment

Also, fixed temperature release may be located inside small rooms.

9. Review the layout to see that it is reasonable. The maximums stated are conservative, but due to variance in natural weathe

conditions, maximum and minimum spacing is recommended to be used.

When tank height exceeds 20 ft, (6.1 m) add additional rings around the tank at a maximum of 20 ft. (6.1 m) for Model C-1 or 16 ft (4.9

m) for Model C-2 vertical intervals. Stagger the releases. When multiple rings or releases are used, the top ring should be 1 ft (.30 m

minimum above top of tank. The other release rings should be spaced equally between bottom of tank and top ring. On tanks over 30

ft (9.1 m) and to 60 ft (18.3 m) in diameter, locate a release over top or center. Over 60 ft (18.3 m), use three releases in a triangula

pattern. If possible, space releases around tank so they can see each other. Use a 160 F (71 C) xed temperature release unde

the center of a small elevated tank or pilot heads on 10 ft (3.0 m) centers for a larger elevated tanks. For high risks, use releases

under tanks.

Locate releases 1 ft (.30 m) minimum above

top of tank or equipment. Equipment should

fall substantially inside the area outlined. f

height exceeds the maximum, add additional

rings of releases around the equipment at a

maximum of 20 ft. (6.10 m) for Model C-1

or 16 ft. (4.9 m) for Model C-2 vertical in-

tervals. Stagger lower releases in alternate

location. When multiple rings or releases are

used, the top ring should be 1 ft. (.30 m)

minimum above equipment top, and the

other rings should be spaced equally be-

tween top ring and the equipment bottom.

t may be desirable to place a 160 F (71 C)

fixed temperature release under the center

of elevated tanks or equipment. Use one re-

lease in each 10 ft x 10 ft (3 m x 3 m) square.

For high risks, use releases under tanks.

NOTES

1. Locate releases close to underside of solid floor or roof.

2. f maximum allowable, A and B dimensions, place interior

release outside of exterior line of releases, then interior

releases are not needed.

3. Where multiple floors are involved, treat each floor as

a separate building. f height between floors exceeds

the maximum, add additional releases below in such a

manner that vertical distance between releases does not

exceed maximum height between floors.

4. Where top of building is open or grating, locate releases 1 ft

(.30 m) minimum above top of grating. Locate releasesbelow intermediate grating floors.

5. Locate releases 1 ft (.30 m) minimum above top of equip-

ment.

6. f height of equipment exceeds the maximum, add ad-

ditional releases directly above lower releases at a maxi-

mum of 16 ft (4.8 m); vertical intervals. Space releases

equally between the top row and the equipment bottom.
